Instructor Erika Biga Lee’s son Max is a huge fan of Godzilla — he’s gone to the Godzilla museum in Chicago twice and even dressed up as the monster for Halloween. So when she decided to bring him along to one of her classes when he had a day off of school, it was only natural that he wanted to bring his costume with them, too. The result was absolutely adorable.

According to Nathaniel Ferguson, the undergraduate instructor that tweeted out the photos, Max hadn’t originally planned on wearing the costume. But after some coaxing from his mother and the other students, he donned the suit and walked around the classroom.

Overall, Max got a positive response from the students — in fact, that last photo was of a girl tearing up over how cute he was.

“Mostly the reactions were very good, lots of holding back tears or ‘aww’ing,” Ferguson said. “Some students didn’t really care one way or another, but the reactions are all pretty evidenced in the photos.”

Of course, people on Twitter were just as moved by the mini Godzilla as the rest of us.

@ngmferguson Idk what it is about that last pic but it is too adorable!!!!
